加入代碼中有這樣一個路由需要渲染;render(    <Router history = {browserHistory} >     <route path ="/" component={App} >         <IndexRoute  component={Home} />         <route path ="/jianjie" component={jianjie} />         <route path ="/yewu" component={yewu} />         <route path ="/lianxi" component={lianxi} />         <route path ="/about" component={About} />         <route path ="/test" component={test} />     </route></Router>, ele)但是App組件是這樣的；import React ,{ Component }from 'react';import Nav from './nav';import Foot from './foot';class App extends Component{     constructor(props){        super(props);     }     render(){        return (            <div>                 {this.props.name}                <Nav />                 {this.props.children}                <Foot />             </div>         )     } }export default App;App組件中這個 {this.props.name}是通過外面參數傳遞進來的，但是上面的代碼中怎么向App傳遞參數呢；如果是單純的渲染App可以這樣寫：render(    <App {...props}/>, ele)希望有知道的朋友幫忙解答一下啊
